xen_sysexit and xen_iret were doing essentially the same thing. Rather than having a separate implementation for xen_sysexit, we can just strip the stack back to an iret frame and jump into xen_iret. This removes a lot of code and complexity - specifically, another critical region. Signed-off-by:

split out x86 specific part from grant-table.c and allow ia64/xen specific initialization. ia64/xen grant table is based on pseudo physical address (guest physical address) unlike x86/xen. On ia64 init_mm doesn't map identity straight mapped area. ia64/xen specific grant table initialization is necessary. Signed-off-by:

If an event comes in while events are currently being processed, then just increment the counter and have the outer event loop reprocess the pending events. This prevents unbounded recursion on heavy event loads (of course massive event storms will cause infinite loops). Signed-off-by:

Make KERNEL_PGD_PTRS common, as previously it was only being defined for 32-bit. There are a couple of follow-on changes from this: - KERNEL_PGD_PTRS was being defined in terms of USER_PGD_PTRS. The definition of USER_PGD_PTRS doesn't really make much sense on x86-64, since it can have two different user address-space configurations. I renamed USER_PGD_PTRS to KERNEL_PGD_BOUNDARY, which is meaningful for all of 32/32, 32/64 and 64/64 process configurations. - USER_PTRS_PER_PGD was also defined and was being used for similar purposes. Converting its users to KERNEL_PGD_BOUNDARY left it completely unused, and so I removed it. Signed-off-by:
